A. $CH_3COOH \gt HCl \gt NH_3 \gt NaOH$
B. $HCl \gt CH_3COOH \gt NaOH \gt NH_3$
C. $NaOH \gt NH_3 \gt HCl \gt CH_3COOH$
D. $NaOH \gt NH_3 \gt CH_3COOH \gt HCl $


参考答案:  D


本题详细解析:
NaOH is a strong base mn0 :7evhp 3rfand has a high pH,$NH_3$ is a weak base with a lower pH than NaOH.$CH_3COOH$ is a weak acid, HCl is a strong acid and so has the lowest pH.
